Description

Multi-functional phlegm suction device of nursing internal medicine

Technical Field

The invention relates to the technical field of medical equipment, in particular to a multifunctional sputum suction device for a nursing department.

Background

The self-defense mechanism of the respiratory system depends on ciliated columnar epithelium on the mucosa of trachea and bronchus and the structure of goblet cells secreting mucus, ciliated cells move rhythmically from inside to outside to drive particles deposited on the mucosa to be discharged to the throat along with the mucus, and when the mucus is accumulated into phlegm, the phlegm is reflected by cough and discharged out of the body. Only under normal mucociliary transport function will secretions in the distal airways be transported to the larger airways and then cleared via the cough reflex. However, for a patient with an artificial airway such as a tracheal cannula or a tracheal cannula, the artificial airway ensures the smoothness of the airway and saves the life of a critically ill patient, but seriously damages the self-owned cilia-mucus defense mechanism of a respiratory system and increases the occurrence of pneumonia related to bacterial colonization and a respirator. The patient who opens artificial airway need avoid the harm that the sputum pile up and cause with the help of external attraction.

We find in clinical use, inhale the relation that phlegm pipe and collecting pipe often are the one-to-one among the prior art, often one inhale phlegm device and can only carry out a patient's phlegm operation of inhaling simultaneously, must give the oxygen of high concentration around inhaling the phlegm, equipment is numerous, the intangible work load that has increased, it is very loaded down with trivial details to inhale phlegm operation, and do not divide and go round the clock, very big increase the burden of protecting the worker, it often can be mixed with the germ gas to inhale the in-process of phlegm, if do not handle and probably harm medical personnel's healthy, therefore, need a neotype multi-functional phlegm device of inhaling of nursing internal medicine now to solve the problem that meets.
